The coating material is coated on a crankshaft neck surface and/or bearing bush surface between a crankshaft neck and a bearing bush (tile), so that a protective coating which is lubricant enough, and not easy to wash off or damage, and can bearing extremely high temperature is provided under the condition that the engine oil cannot provide effective lubricating due to poor quality, or cannot provide an enough lubricating effect between the crankshaft and a connecting rod due to reduction of the engine oil, the coating material has excellent waterproof properties, anti-rust characteristics, anti-corrosion property, and micro-grinding resistance on metal parts, can form solid dry film lubrication under the environment above 200 DEG C, and can play the roles in lubricating and preventing metal from being locked by sintering at the temperature which can be up to 1400 DEG C, and the locking phenomenon between the crankshaft and the connecting rod caused by dry friction between the tile and the crankshaft is effectively avoided.
Description
Technical field
The present invention relates to coated material field, particularly a kind of for for preventing the coated material of engine crankshaft locking.
Background technology
Piston, linkage assembly are connected on bent axle, the pressure that bent axle is producing while bearing fuel mixture burning by piston and connecting rod, and the to-and-fro movement of piston is changed into and rotatablely moved.A slide unit between crankshaft-and-connecting-rod, becomes bearing shell, and it forms a sliding surface bearing together with machine oil.Between the bent axle of Otto cycle engine and big end, adopt sliding friction, in crank pin end pore, have upper and lower two semicircular tiles (namely bearing shell), a sliding surface bearing of the common formation of tile and machine oil.Tile is made by stalloy, and is cast with in steel disc inner side the alloy layer that reduces friction, and this alloy layer can play the effect that keeps oil film, reduces friction.The inner side of tile is also processed with oil groove, in order to store machine oil, guarantees lubricated reliably.One end of tile is fixed on the inwall of big end, and the other end is connected with bent axle by oil film.Gap between tile and bent axle is very little, and by after suitable break-in, this gap can be very even.In this minimum gap, have the uniform oil film of one deck, these machine oil oil films just serve as the effect of steel ball in two-cycle engine rolling bearing.We know, the normal idling of engine generally, on the 800-900 right side of turning left, that is to say that between engine crankshaft and connecting rod, per minute will rotate about 800-900 time.This is still at idling mode, if it is even higher that high engine speeds running per minute at least will reach the rotating speed that 4000-5000 turns, in the face of like this high rotating speed, the friction between tile and neck of bent axle is very violent, and the machine oil of now bearing lubrication just seems extremely important.Once engine lacks oil lubricating, just in rolling bearing, do not had steel ball general seemingly, between tile and neck of bent axle, can produce metal to-metal contact, this situation is very terrified: friction so fast, in the wearing and tearing of extreme aggravation tile, also can produce amount of heat, thereby cause tile to burn, Here it is our Bearing score of often saying.Once not only there is no machine oil between crankshaft-and-connecting-rod, and the alloy layer of antifriction be lubricated all loses, can cause locking between crankshaft-and-connecting-rod.And the in the situation that of excess Temperature, bent axle radially radius increases, and with bearing shell (tile) swelling, is also one of reason causing locking between bent axle and connecting rod, the lubricated inadequate generation of locking situation that also easily causes that machine oil inferior causes in addition.
Therefore, what need to solve is can not provide effectively lubricating or engine motor oil to reduce and provide enough lubricated between can not be to crankshaft-and-connecting-rod in the situation that in engine motor oil poor quality, how to avoid producing metal to-metal contact between tile and bent axle and finally causes the generation of locking phenomenon between crankshaft-and-connecting-rod.
Summary of the invention
